# [NAME](#NAME)

gnutls\_x509\_rdn\_get\_by\_oid - API function

# [SYNOPSIS](#SYNOPSIS)

**#include <gnutls/x509.h>**

**int gnutls\_x509\_rdn\_get\_by\_oid(const gnutls\_datum\_t * idn, const char * oid, unsigned indx, unsigned int raw\_flag, void * buf, size\_t * buf\_size);**

# [ARGUMENTS](#ARGUMENTS)

[const gnutls\_datum\_t * idn](#const)

should contain a DER encoded RDN sequence

[const char * oid](#const~2)

an Object Identifier

[unsigned indx](#unsigned)

In case multiple same OIDs exist in the RDN indicates which to send. Use 0 for the first one.

[unsigned int raw\_flag](#unsigned~2)

If non-zero then the raw DER data are returned.

[void * buf](#void)

a pointer to a structure to hold the peer's name

[size\_t * buf\_size](#size_t)

holds the size of *buf*

# [DESCRIPTION](#DESCRIPTION)

This function will return the name of the given Object identifier, of the RDN sequence. The name will be encoded using the rules from RFC4514.

# [RETURNS](#RETURNS)

On success, **GNUTLS\_E\_SUCCESS** (0) is returned, or **GNUTLS\_E\_SHORT\_MEMORY\_BUFFER** is returned and * *buf\_size* is updated if the provided buffer is not long enough, otherwise a negative error value.
